Abstract

The invention provides a knitting-yarn maintenance cutting device and a flat knitting machine. A drive pin parts (15) is mounted about the front end of a driving lever (14) mounted on a output axis (13a) as motor (13) of driving source. The drive pin parts (15) is commonly inserted into slot (16a) and arc slots (17a),(18a) of a bonding parts (16) for cutting piece and two bonding parts (17),(18) for bend needles. The bonding parts (16) for cutting piece conveys driving power for making the cutting piece (10) act through output of motor (13). The bonding parts (17),(18) for bend needles transfer and converse the driving power for making the bend needles (11),(12) selectively act through output of motor (13). When each of the bend needles (11),(12) descends, the upper hooked part respectively clamps knitting yarn (6),(7) between the yarn hodling levers (19),(20) to maintain.

Description

technical field [0001] The present invention relates to a knitting yarn holding and cutting device for holding and cutting a knitting yarn supplied from a yarn supply port for knitting a knitted fabric, and a flat knitting machine provided with such a knitting yarn holding and cutting device. Background technique [0002] Conventionally, a yarn gripping device has been used for cutting and separating each product while continuously knitting products with a flatbed loom (for example, refer to Patent Document 1). In the yarn gripping device disclosed in Patent Document 1, a pair of jaws are raised to the path of the knitting yarn from the knitting end of the knitted fabric to the yarn supply port in an open state from the bottom of the tooth gap or the bottom of the tooth gap side end, Close the claws to grasp, and lower the claws holding the knitting yarn to hold the knitting yarn. The lifting action of such jaws is performed by converting the rotational output of the motor ...
